Induction Aluminum Melting Furnace

How it works

It is ideal for aluminum recycling plants, small foundries, die-casting workshops, metal processing factories, and laboratory melting research. It provides high-quality molten aluminum for casting, ingot casting, and metal forming production lines.

An induction furnace melts by putting the metal inside the magnetic field of a coil. Alternating current in the coil induces currents in the charge itself, so the metal heats from the inside out and the melt is stirred electromagnetically as it forms. There is no flame and no combustion gas in contact with the metal, which is why losses and gas pickup are lower than in a fuel-fired furnace.

Frequency sets the character of the melt. Medium frequency couples efficiently into a charge of mixed piece size and gives the stirring that homogenises alloy, while higher frequency concentrates power into smaller volumes. Power supply, coil, capacitor bank and cooling are designed as one system — changing furnace size without changing the power pack is what produces disappointing melt rates.

Key features

• High Efficiency & Energy Saving: Adopts advanced IGBT medium frequency technology, fast melting speed, high thermal efficiency, and low power consumption
• Uniform Melting: Electromagnetic stirring ensures even temperature and composition, reducing oxidation burning loss effectively
• Precise Temperature Control: Stable temperature control system guarantees accurate melting temperature
• Safe & Reliable: Full protection against over-current, over-voltage, water shortage, over-temperature, and leakage
• Easy Operation: Compact structure, small footprint, simple start-stop, and convenient tilting for molten aluminum discharge
• Eco-friendly: No smoke, low noise, clean working environment, suitable for long-term industrial use

How to choose induction melting

• Start from the pour weight and the melt time you need, then work back to installed power; furnace capacity alone tells you the crucible volume, not the melting rate.
• Check the transformer and the supply you have. A furnace that needs more kVA than the site can deliver is a site upgrade, not an equipment purchase.
• Decide on tilt arrangement (hydraulic or manual), because it determines the pouring layout and the ladle handling around the furnace.
• Plan cooling as part of the package. Closed-loop cooling is what allows the power supply to run continuously without depending on the local water quality.
